7.1.2 Recommended filter intervals (gradient parameters)
In the start step of a tightening program, the calculation of the gradient values is parameterized using
gradient parameters. This is particularly important with yield-point controlled tightening processes. One
of these gradient parameters is the so-called filter interval that is used to improve suppression of output
drive-specific interferences in the gradient signal. The filter interval leads to an extended smoothing of the
gradient graph, but also delays gradient evaluation.
Information on the gradient parameters in general and on the filter interval in particular can be found in
the "Project planning" documentation of the Rexroth Tightening System 350.
The filter interval depends on the mechanical output drive component. Table 7–1 shows the filter intervals
for different output drives recommended by Rexroth.
